Among the "Presentations, guides, and tutorial materials"
indexed at
http://www.w3.org/XML/Schema
this seems relevant:
The XML Schema Specification in Context
by Rick Jelliffe, Academia Sinica Computing Centre
2000-02-24 draft only
compares XML Schema with XML DTDs, SGML DTDs, HyTime, and perl
regular expressions
http://www.ascc.net/~ricko/XMLSchemaInContext.html
Also, if you like to "Use the Source, Luke!" you might
like to study a tool that converts DTDs to schemas:
A Conversion tool from DTD to XML Schema in perl; open source.
